Storage requirements are based on the maximum supported resources for each node.

vRealize Operations Manager has a high CPU requirement. In general, the more physical CPU that you assign to the analytics cluster, the better the performance. You must use a minimum of eight physical CPU dual socket hosts, but it is recommended that you use 12 or more physical CPU dual socket hosts.
